There's 'snapshot' functionality coming in https://issues.apache.org/jira/browse/CASSANDRA-279
slated for 0.4, but to my knowledge no toolIng in the works for
later using that data. It should be as simple as tar'ing and
restoring somewhere else after that.

Is there a mysqldump style dump/backup command?

If you run 'ant clean' before running ant or Cassandra, it will ensure
that no old artifacts are still around from the code that could be
causing problems.
To dump the db, just delete the db directories. There should be
tooling for this in the future, but that's the most surefire way to
know that you are starting fresh for now.
